Walther PPK Problems

I'm at the range for the first time, I slingshot one in the chamber, take the safety off, pull the trigger, and "click." I look at the round and there is a pretty significant indentation in the primer. I load the round again, pull the trigger, and it goes off.

The same thing happened 60 rounds later with another brand of ammo.

This gun is very tight. I have it well-lubricated, but in the first 80 rounds, I had four failures to feed because the rim would not properly slide underneath the extractor. Here is a photo of this phenomenon:

I suspect the problem is that the loaded chamber indicator is getting in the way, as can be seen in the photo. Any other ideas?

Since shooting it, I have degreased the firing pin channel and now it is much smoother. Before when I pressed the hammer up against the firing pin it was crunchy, with two or three stages. Now it is just one stage and smooth.

Only thing I notice is using "crap" rounds will not push the slide back enough to actually load another round. Even after breaking the weapon in, these were made to use a more "hot" euro round so just be careful using the cheap stuff.
